Hello, I can assure you that with my twelve years of experience as a Web Designer and the many skills I have developed, qualify me to successfully migrate your 4 Wordpress websites within 2 hours. I guarantee that my services will meet or surpass your expectations.
I've completed hundreds of WordPress migrations. I would first create new Databases for each website and import the db backups, than the website files via FTP. If any paths need to be change due to the new host, i will create a sql query to do.
Time Frame: 2 hours
